In the above table the inorganic matter is not seperately considered, 

 it being distributed among the several organic bodies. By rejecting tho 

 cobs of 1000 Ibs. of dry ears about 200 Ibs. of organic mattei is lost 

 which consist of 13}^ Ibs. of sugar and extract, 227 * Ibs. of fibre, 45)^ 

 Ibs. of wator soluble in potash, l}o Ibs. of albumen, % Ib. of casein, 

 2.31 Ibs. of gum or dextrine, 1.8 Ibs. of resin, and 7.4 Ibs. of glutinous 

 matter. Hence the cob, although not rich in nutritive matter, can by 

 no means be said to be destitute of these proximate principles which 

 go to support respiration and sustain animal heat, and those which are 

 capable of being transformed into nerve, muscle, etc., and the phos 

 phates which contribute so largely to the formation of bone.

Of all the twenty -seven varieties of corn examined by Dr. Salisbury, 

 the Rhode Island Sweet is the richest in albumen, oil, and dextrine, and 

 the most deficient in starch. Asa general rule, those varieties with 

 full corneous kernels are richer in the nitrogenized bodies and oil, and 

 less rich in starch than the indented kinds; and of the corneous sorts 

 with distended grains, the yellow seems to be richer than the white in 

 oil, and those bodies which contain nitrogen, and less rich in starch. 



According to Fresenius, the oil of corn consists of :

Oxygen, - - 8.79
